Thanks for these responses. I had no idea what the trajectory was for round ball. So I will move out to 50 yds, 75 etc and see where I am before I mess with the sights. I may want to try hunting with this gun next season and according to your responses I will have to increase the charge to make the round effective for a kill. In New England you rarely get a shot at greater than 50 yards. This gun is fun to shoot with the current target load and I may get my wife to try it.
